jicgeometry¶
Module for geometric operations.
The module contains two classes to perform geometric operations in 2D and 3D space:
A 2D point can be generated using a pair of x, y coordinates.
>>> p1 = Point2D(3, 0)
Alternatively, a 2D point can be created from a sequence.
>>> l = [0, 4]
>>> p2 = Point2D(l)
The x and y coordinates can be accessed as properties or by their index.
>>> p1.x
3
>>> p1[0]
3
Addition and subtraction result in vector arithmetic.
>>> p1 + p2
<Point2D(x=3, y=4, dtype=int)>
>>> p1 - p2
<Point2D(x=3, y=-4, dtype=int)>
Scalar multiplication is supported.
>>> (p1 + p2) * 2
<Point2D(x=6, y=8, dtype=int)>
Scalar division uses true division and as a result always returns a 2D point of
dtype float.
>>> p1 / 2
<Point2D(x=1.50, y=0.00, dtype=float)>
It is possible to calculate the distance between two points.
>>> p1.distance(p2)
5.0
Points can also be treated as vectors.
>>> p3 = p1 + p2
>>> p3.unit_vector
<Point2D(x=0.60, y=0.80, dtype=float)>
>>> p3.magnitude
5.0
